TY - JOUR T1 - IMPEDANCE IMAGE RECONSTRUCTION WITH ARTIFICIAL NEURAL NETWORK IN ELECTRICAL IMPEDANCE TOMOGRAPHY AU - Kilic, Beyhan PY - 2019 DA - December DO - 10.36222/ejt.650616 JF - European Journal of Technique (EJT) JO - EJT PB - Hibetullah KILIÇ WT - DergiPark SN - 2536-5010 SP - 137 EP - 144 VL - 9 IS - 2 LA - en AB - Electricalimpedance tomography views the electrical properties of the objects byinjecting current with surface electrodes and measuring voltages. Then using areconstructing algorithm, from the measured voltage-current values,conductivity distribution of the object calculated. Finding internalconductivity from surface voltage-current measurements is a reverse andill-posed problem.Therefore,high error sensitivity, and making approximations in conceiving complexcomputations cause to limited spatial resolution. The classic iterative imagereconstruction algorithms have reconstruction errors. Accordingly, Electricalimpedance tomography images suffer low accuracy. It is necessary to evaluatethe collected data from the object surface with a new approach. In this paper,the forward problem solved with the finite element method to reconstruct theconductivity distribution inside the object,the reverse problem solved by the neural network approach. Image reconstructionspeed, conceptual simplicity, and ease of implementation maintained by this approach.
